Type Marking Ordering Code x GMR S 4 s Q62705-K5002 x new type The GMR S 4 is an angle sensor based on sputtered metallic multilayer technology. The outstanding feature of this magnetic sensor is the fact that it is sensitive to the orientation of the magnetic field and not to its intensity as long as the field is in a range between 5 … 15 kA/m.
